To all whom 'it may concern:

Be it known that I', OsKAn SCHAUMANN, a subject of the German Emperor, and residing at Steglitz, near Berlin, Germany, have invented certain new and useful Improvements in Armor-Plating, of which the following is a specification.

My invention relates to armor-plating,

and a primarv object is to provide ballproof armor-plating consisting of a hard inelastic outer plate and inner plates becoming specilically lighter in the direction through the armor-plate from the side thereof on which the projectile impacts, so that in this inanner a support of compara.- tively great strength and small Weight is made for the top layer of the wall formin the armor-plate proper and the Wei ht o the entirearmor-plate is materially imin` ished.

In one special practical form of my invention the armor-plating consists of individual supciposed plates which are specifically lighter in the direction through the plate from the impact side, whereas in an other practical form all the plates are so united by siiitably arranged rivets, screws or the like that they form one absolutely rigid body. y

AccordingV to my invention, in order to obtain perfect security from penetration and perforation of the armor-plating by pointed projectiles, I may provide on the arnror-plate proper an additionalthin late ofgrea't hardness, on which', the point o the -I projectile becomes split when impacting, so that after the projectile has perforated this tliin plate of great hardness 1t onlTyY acts on the armor-plate proper as a bluntor pointless projectile and cor'isequently is stopped and leaves solely a slight impression. In one very special practical form of my .improved armor-platingthe thin facing of great hardness has at the face against the armor-plate a less degree of hardness than at the impacting face of t-he projectile, whereby the protective facing-plate is prevented from being :cracked when the rojeclile impacts thereon, which might ot erwise readily occur because a plate of great hardness readily cracks under the action of a blow.4 L

In another very practicalfol'm oftheinvention, 'an insertion of softer material, such as aluminium, silk, asbestos or the like,

p plate, its

Some embodimentsof m invention are represented diagammatical y and by Way .of example on the accompanying di'awingsn" Figure 1 is a section showixg one fofm of my improved armor-plating, ig; 2 is a like view of my arnior-4 loting provided with the newprotective acing, and Fig.- 3`isV a like v'ievv showing the to plate of the armor-plate proper, on which a pointed projectile, Whose point was previously dc'- stroyed by the new protectlve facing, has impacted. f V

Referring firstly to Fig. 1, a. steel plate cY forms the impacting side for the pro ectile' an alinninium plate d being placed hin this and a Celluloid or' horn plate .f behind the latter.

The 'manner in which' m improved armor-plating acts'is very stri ng because the same steel plate c when exposed alone to the shot is simply penetrated by the projectile butoilers complete resistance at once to the shot 4as soon as the plates d, f`con sisting, according to my invent-ion, of specifically lighter material, or other plates corres ending Vto the same conditions are placedp under and firmly connected with the steel late c.

provide otside the layer c, a protective plate or facing a, whose face a', on which the projectors impact, is glass-hardI whereas thesurface,a*, facing-the armorI plate proper, is onlytoughhard or ductile. Be tween ,the plate or facing a, and the la er c, is a layer of softer'material b, consisting for example of aluminium, silk fabri c, asbestes or other Vsuitablematerial. Y

Now when a pointed 'projectile impacts in the direction of arrow P on `this armoroint will split at the glass-hard face a. win to the ductile structure of the steel or the iks at the-.other side of this facing, plate a` is prevented Afrom cracking, and the "rojectile, after having lost its oint at p ate a, arrives as la blunt or pointess rojecti'le on the plate c forming part of t e armor-plate proper. This armorplate comprising, for example, the plates c, d, and f can 'only be penetrated by a ne erring eifrig. 2, it win be noted amt y ico i plate,
